==Self-fulfilling prophecy==
A [[self-fulfilling prophecy]] may be a form of causality loop. [[Predestination]] does not necessarily involve a [[supernatural]] power, and could be the result of other "infallible foreknowledge" mechanisms.<ref>{{cite journal |last=Craig|first=William Lane|year=1987 |url=http://www.leaderu.com/offices/billcraig/docs/newcomb.html |title=Divine Foreknowledge and Newcomb's Paradox |journal=Philosophia |volume=17 |issue=3 |pages=331–350 |doi=10.1007/BF02455055|s2cid=143485859}}</ref> Problems arising from infallibility and influencing the future are explored in [[Newcomb's paradox]].<ref>{{cite book|last=Dummett|first=Michael|title=The Seas of Language|isbn=9780198240112|year=1996|publisher=Oxford University Press|pages=356, 370–375}}</ref> A notable fictional example of a self-fulfilling prophecy occurs in the classical play ''[[Oedipus Rex]]'', in which [[Oedipus]] becomes the king of [[Thebes, Greece|Thebes]] and in the process unwittingly fulfills a prophecy that he would kill his father and marry his mother. The prophecy itself serves as the impetus for his actions, and thus it is self-fulfilling.<ref>{{citation|last=Dodds|first=E.R.|year=1966|title=Greece & Rome}} 2nd Ser., Vol. 13, No. 1, pp. 37–49</ref><ref>{{cite book|last1=Popper|first1=Karl|title=Unended Quest: An Intellectual Autobiography|date=1985|publisher=Open Court|___location=La Salle, Ill.|isbn=978-0-87548-343-6|edition=Rev.|page=139}}</ref> Similarly, the book series ''[[Harry Potter]]'' deals with self-fulfilling prophecies. The impetus of the plot begins when the antagonist, Lord Voldemort, hears of a prophecy predicting his downfall. Seeking to quash the resistance before it's entrenched, he attacks and kills Harry's family, thinking Harry is the central figure in the prophecy. When he fails to kill the infant Harry however, he implants a fierce desire for justice and revenge in the prepubescent Harry that ultimately serves as the catalyst for Voldemort's death at the end of the series, thus becoming a self-fulfilling prophecy. The movie ''[[12 Monkeys (film)|12&nbsp;Monkeys]]'' heavily deals with themes of predestination and the [[Cassandra (metaphor)|Cassandra complex]], where the protagonist who travels back in time explains that he can't change the past.<ref name="Klosterman" />
